初次接触一种东西，总是会遇到很多意想不到的问题，尤其是技术性的问题，细节多，规则也多，一步一个陷阱，能够尽快的理出思路，找到头绪，则是快速解决问题的关键。

最近开始基础openCV，希望了解一点里面的算法，用于自己的产品中，然而，初次接触，再加上，是在之前很少接触的windows平台上，真是吃尽苦头。

最近版本的openCV2.0提供的动态链接库，看是活生生的存在于bin目录下，编译链接，运行程序时却总是提示找不到，而VS的提示也让人摸不着头脑，明明是某函数不能加载，却提示成另外一个函数找不到。一气之下，打算重新编译一下opencv。

由于也是初次使用微软的编译环境，一切都得学习，于是百度+google，然而搜到的内容大多是将如何配置一个使用opencv进行应用开发的配置，很少有文章涉及opencv的编译。想来技术这种事情本来就是，对于过来人，举重若轻，对于菜鸟，真是泰山压顶！

经历了很长时间的闭门羹后，终于还是在opencv自带的doc目录下，发现了编译的提示：

windows和linux的步骤混合在一起。看起来也不轻松，下面是我整理后的步骤（一共11步）：

build the openCV step by step:

1. download the openCV and installit, assuming: D:/Program Files/OpenCV2.0

2. download the cmake and installit.

3. download VS studio and installit

4. create a directory under theopencv directory: D:/Program Files/OpenCV2.0/release

5. >cd D:/ProgramFiles/OpenCV2.0

6. execute D:/ProgramFiles/OpenCV2.0 ../

7. the cmake will generate theproject files for VS under D:/Program Files/OpenCV2.0/release

get thefollowing output:

D:/Program Files/OpenCV2.0/release>cmake-D:CMAKE_BUILD_TYPE=RELEASE ../

8. get into directory release andopen the VS, compile all

9. after complete the compile, theThere are several directories will be created under the D:/ProgramFiles/OpenCV2.0/release:

D:/ProgramFiles/OpenCV2.0/release/lib/debug – the leading description of the opencv dlls

D:/ProgramFiles/OpenCV2.0/release/bin/debug – the dll directory, adding it to the PATHenvironment variable.

10. start to use the openCV forbuild one’s own application, create a VS project,

“配置属性”---“连接器”---“常规”的“附件库目录”：

D:/ProgramFiles/OpenCV2.0/release/lib/debug

Add followinglibs to “配置属性”---“连接器”---“输入”的“附加依赖项”

"cv200d.lib "

"cvaux200d.lib"

"cvhaartraining.lib"

"cxcore200d.lib"

"cxts200d.lib"

"highgui200d.lib"

"ml200d.lib"

"opencv_ffmpeg200d.lib"

"libml200.dll.a"

11. environment is ok now, you getthe ball.
